What You'll Learn
Use the right primer and paint for your needs
Painting interior plastic is a great way to transform the look of your space, but it's important to use the right primer and paint to ensure a long-lasting and flawless finish. Here are some tips to help you choose the right products for your needs:
First, identify the type of plastic you are working with. Different plastics require different preparation methods and compatible primers and paints. Check the markings on the back of the plastic piece to determine the type of plastic. Common types include ABS, PVC, TPO, EPDM, PP, and polypropylene.
Once you know the type of plastic, choose a primer that is specifically designed for that type of surface. A good primer will promote adhesion and create a durable base for your paint. For example, if you are working with PVC pipes, a primer like Rust-Oleum Specialty Plastic Primer, which is designed for PVC and other hard vinyl plastics, will ensure optimal adhesion and a smooth finish.
If you're looking for a flexible coating for your interior plastic, consider a product like SEM Color Coat. It is a permanent coating that can be applied to plastic, vinyl, carpet, and velour. It is available in a range of colours or can be custom-mixed to match your desired shade. When applying Color Coat, follow the manufacturer's instructions, which may include cleaning the surface with a specific cleaner or using a protectant to prevent fading.
For a more customizable option, NAPA paint products offer excellent colour-matching services for vehicle interiors. You can get aerosol paint cans filled with your exact manufacturer colour by providing the paint code or a colour-chip match. NAPA's two-part application process involves a basecoat paint and a separate clear coat, which provides added protection against rust and scratches.
Remember, using the right primer and paint for your specific plastic surface will ensure a long-lasting and professional-looking finish. Take the time to research and choose the right products, and don't be afraid to seek advice from experts or other DIY enthusiasts.

Prepare the surface
Preparing the surface is a critical step in painting interior plastic. It ensures that the paint adheres properly and helps create a smooth and durable finish. Here is a step-by-step guide to preparing the surface for painting:
Firstly, it is important to identify the type of plastic you are working with. Different types of plastics require different preparations. You can usually identify the type of plastic by checking the markings on the back of the plastic part. Common types of plastic used in interior applications include ABS, PVC, TPO, EPDM, and PP.
Once you have identified the type of plastic, the next step is to thoroughly clean the surface. Use a mild soap or a specialised plastic cleaner, such as SEM Soap or Plastic & Leather Prep, and a grey scuff pad to scrub the surface. Pay close attention to textured or recessed areas, as dirt and grime can build up in these areas. Rinse the surface with water or wipe away any residue with a damp cloth and allow it to dry completely.
After cleaning, you may need to apply a primer to promote adhesion and ensure the paint sticks properly. The type of primer you use will depend on the type of plastic you are painting. For ABS, PVC, and similar plastics, you can apply a medium wet coat of Sand Free. While it is still wet, apply a light coat of Colour Coat. For TPO, EPDM, PP, and other similar thermoplastics, use a Plastic Adhesion Promoter or XXX Adhesion Promoter. Apply one light coat, let it flash for 5 minutes, and then apply a full wet coat.
Before painting, it is important to protect the areas you do not want to paint. Use painter's tape and plastic sheets or shopping bags to cover these areas. Apply the tape to create sharp edge lines between the painted and non-painted areas. This will help ensure a clean and precise paint job.
Finally, when you are ready to paint, always refer to the paint manufacturer's instructions for the best results. Shake the can periodically during the paint job to prevent runs and sags. Apply multiple light coats of paint, rather than one heavy coat, to ensure full coverage and eliminate drips. Allow each coat to dry completely before applying the next one.

Remove parts you'll be painting
When it comes to painting interior plastic, one of the most important steps is to remove the parts you'll be painting. This will ensure that you get a clean, professional-looking finish. Here's a step-by-step guide on how to remove the parts you'll be painting:
Begin by gathering all the necessary tools and materials, including a screwdriver, a pry bar, and a soft cloth. You'll also need a safe, flat surface on which to place the parts once they're removed. Before removing any parts, it's important to clean the area to ensure that no dirt or debris gets caught in the mechanism or affects the painting process. Use a soft cloth to wipe down the area, and make sure it is completely dry before proceeding.
Locate the parts you'll be removing and identify the type of fasteners or clips holding them in place. Common fasteners include screws, bolts, or snap-on fittings. Carefully remove these fasteners, making sure not to lose them, as you'll need to put them back later. Place them in a small container or bowl to keep them safe. Some parts may have additional clips or fittings holding them in place. Use a pry bar or flat-head screwdriver to carefully disengage these clips without damaging the surrounding area.
Once all the fasteners and clips have been removed, gently pull the part away from the vehicle, being mindful of any wiring or other components that may be attached. Place the part on your prepared surface, being careful not to scratch or damage the surface. If there are any wires or connectors attached to the part, carefully disconnect them, making note of their orientation for reassembly.
Finally, once the part has been removed, take the opportunity to thoroughly clean it and prepare the surface for painting. Use a mild detergent and water to remove any dirt, grease, or residue, and ensure the surface is completely dry before priming and painting. By carefully removing the parts you'll be painting, you can ensure a high-quality finish and protect the surrounding areas from accidental paint splatters or damage.

Apply adhesion promoter
Painting plastic interior parts is different from painting the outside of a car because interior parts are often made of plastic. Different plastics require different prep work. To promote adhesion on plastics, such as ABS, PVC, or other similar plastics, apply a medium wet coat of Sand Free. While still wet, apply a light coat of Color Coat. Avoid applying the first coat of Color Coat too heavily or sagging could occur. As Sand Free evaporates, Color Coat is drawn into the surface, resulting in excellent adhesion.
To promote adhesion on plastics, such as TPO, EPDM, PP, or other similar thermoplastics, use a plastic adhesion promoter. Apply one light coat, let flash for 5 minutes, and then apply one full wet coat. Allow this coat to flash for 10-15 minutes, but no longer than 30 minutes before top coating. If the type of plastic is unknown, place a drop of acetone on the back of the plastic and rub it with your finger. If the plastic smears and melts, use Sand Free. If acetone does not have an effect on the plastic, use a plastic adhesion promoter.
Adhesion promoters improve the adhesion of enamel and lacquer topcoats to all surfaces, including plastic and chrome. They are all-purpose clear primers ideal for both interior and exterior applications. Prepare the surface by removing loose paint, dirt, rust, grease, and wax. For best results, use a grease and wax remover to clean the surface. To spray, hold the can parallel and 8–10 inches from the surface and use an even, sweeping motion. To avoid runs and sags, apply 2–3 light coats, allowing 3 minutes between each coat. Apply the top coat within 10 minutes of the last adhesion promoter coat.
Adhesion promoters are a must-have for anyone looking to improve paint adhesion. They create a smooth, strong bond between the surface and the paint, ensuring the finish stays intact. Adhesion promoters are easy to use and cover a good area. They dry quickly, so you don't have to wait long before applying the top coat.

Use multiple light coats of paint
Painting plastic is a challenging task due to the material's chemical composition and smooth surface, which do not promote good paint adhesion. To achieve a successful finish on interior plastic, it is crucial to apply multiple light coats of paint rather than a single heavy coat. This technique is essential for several reasons.
Firstly, by applying light coats, you allow each layer of paint to dry completely before adding the next one. This prevents the common issue of "orange peel", which occurs when paint dries too quickly before self-levelling, resulting in an undesirable textured surface. By avoiding heavy coats, you give the paint sufficient time to level and dry smoothly.
Secondly, using multiple light coats helps to promote better adhesion. Each light coat builds upon the previous one, creating a stronger bond between the paint and the plastic surface. This is especially important for interior plastic as it can expand and contract at a greater rate than other surfaces, making it more prone to flaking and cracking.
Additionally, spraying or applying light coats of paint helps prevent runs and sags. By not spraying too much paint in one spot or on a cold surface, you can maintain an even finish. If dried runs occur, they can be removed using sandpaper and the area can be repainted.
Finally, applying light coats of paint provides full coverage without drips. This is particularly beneficial when painting furniture or other plastic items with intricate shapes. By painting in light coats, you can ensure the paint adheres evenly to the surface, resulting in a smooth and consistent finish.
In summary, using multiple light coats of paint when painting interior plastic is crucial for achieving a durable and aesthetically pleasing finish. This technique helps prevent common issues such as orange peel, flaking, and dripping, ensuring a long-lasting and professional-looking result.
